" Renewed May 5, 1937 2 Claims.

The invention relates to devices for application to the intake manifoldsof internal combustion engines to thoro-ughly mix the gasoline vapor andair after leaving the carburetor and before 5 entering the engine, andhas for its principal object the provision of a plate adapted to beinstalled in the intake manifold, and provided with a plurality ofopenings, and having mounted on said plate and in line with saidopenings a plurality of independently rotatable agitating devices,consisting of a hub-like sleeve in each instance having radiallyextending blades, the blades being inclined so that the agitatingmembers are impelled by the vapor and air engaging said blades to rotatethe members and thereby agitate the vapor and air to thoroughly mix thevapor and air before entering the cylinders of the engine.

A further object of the invention is provision of a device of thecharacter stated, in which the rotating members are of differentdiameters, the smallest diameter member being nearest to the carburetor,and the other blades of increasing diameter being arranged farther fromthe carburetor.

A further object of the invention is the provision of means for mountingthe mixing members consisting of the provision of spindles mounted onthe plate to receive the sleeves or hubs of the mixing members, theblades being mounted on the sleeves or hubs adjacent to the outer endsthereof, and thus provide for spacing the blades of the adjacentmembers; the inner edges of the sleeves having circumferential flangesthat ride on the adjacent edges of the supporting sleeve, such flangesproviding baiiles at the inner ends of the blades.

The invention will be described in detail hereinafter and will be foundillustrated in accompanying drawing, in which Figure l is a fragmentaryview of a carburetor and intake manifold, shown partly in section, withthe improved gas mixer shown in position therein,

Figure 2 is a plan view of the gas mixer,

Figure 3 is a transverse sectional view on a plane indicated by line 3 3of Figure 2, and

Figure 4 is a fragmentary sectional view on a plane indicated by line 44 of Figure 3.

In the drawing similar reference characters are used to designatecorresponding parts on all of the views.

In Figure 1 the improved gas mixer is shown as applied to an intakemanifold IIJ of an internal combustion engine, Illa indicating thecasing of a carburetor. The improved gas mixer consists of a plate I Iwhich is secured in the intake manifold between the flange I2 and thecarburetor at the intake manifold I0, by means of bolts or screws I3secured to flanges I4 and I5 on the nipple I2 and the intake manifoldIl), respectively.

The plate II is provided with a plurality of openings I6, the numberselected for illustration being two, and each of said openings isprovided with a diametrically disposed cross bar Il to support a spindleI8. Mounted on each of the spindles I8 is a plurality of rotatablemixing members, or fans, or impellers, each of said members having acentral sleeve-like hub I9 and a plurality of blades extend radiallyfrom said sleeve-like hub I9, the blades 20 of the members adjacent tothe plate I I being, as shown, shortest of the blades of the diiferentmembers, the blades of the next member, designated 2l, being slightlylonger than the blades 2|), and the blades of the outer member beinglonger than the blades 2|. By this arrangement it will be apparent thatall the body of vapor and air passing through the openings I6 and intocontact with the members will be thoroughly agitated and mixed beforepassing out of the iniiuence of the mixing members.

The blades 20, 2|, and 22 are inclined laterally, so that they act asimpellers and are rotated by the contact of the air and vapor therewith.Furthermore, the blades, as shown, are arranged adjacent to the upper orouter edges of the sleeve I9, the longer lower portion of the sleeveproviding for spacing the blades of adjacent members from one another,and furthermore, the lower edges of the sleeves are provided withcircumferential flanges 23 that ride on the adjacent sleeve, and saidflanges have the function of baiiies to keep the air and vapor fromfollowing up the surfaces of the sleeves, such baffles serving to throwthe air and vapor outwardly into the vortex of the blade.

I claim as my invention:

1. A gasoline vapo-r and air mixer, comprising a plate adapted to bemounted in an intake manifold of an internal combustion engine andhaving a plurality of openings therein, spindles mounted on said plateand perpendicular thereto, one each of said spindles being mountedconcentric with each of said openings, a plurality of independentlyrotatable sleeves mounted on each spindle, said sleeves beingsuperposed, a plurality of laterally inclined blades extending radiallyfrom each of said sleeves, said blades being spaced and of increasinglength, and the blade nearest the plate being the shortest.

2. A gasoline vapor and air mixer, comprising a plate adapted to bemounted in an intake manifold of an internal combustion engine andhaving a plurality of openings therein, spindles mounted on said plateand perpendicular thereto, one each of said spindles being mountedconcentric with each of said openings, a plurality of superposed,independently rotatable sleeves mounted. on each of said spindles, aplurality of laterally inclined blades extending radially from each ofsaid sleeves and vertically spaced, said blades being adjacent to theends of the sleeves remote from the plate, the other ends of each sleevehaving a circumferential flange to provide a baiile for vapor and air atthe inner ends of the blades, the blades being of increasing length cnthe respective sleeves, and the baldes on the sleeve nearest the platebeing the shortest.
